Purpose and technical function

The lower automatic transmission oil sump in the Mercedes W169 and W245 series plays a key role in the transmission fluid circulation. It is responsible for:

• maintaining the correct amount of oil in the transmission system,
• ensuring a stable level of working medium for the pump and control system,
• sealing the lower part of the gearbox housing,
• creating a mounting space for the filter and fastening elements.

A properly selected automatic transmission oil sump translates into stable transmission operation, correct oil pressure, and predictable gear shifting performance.

Compatibility with automatic transmission

The presented sump is designed for the Automatic transmission type, which means it is matched to the specific housing geometry, mounting hole layout, and oil channels. Using the correct component in an automatic transmission is important for:

• proper sealing of the connection with the gearbox housing,
• appropriate oil routing in the suction and return zones,
• interference-free installation with the filter and internal components,
• maintaining the factory rigidity of the lower gearbox structure.

Proper fitment for the automatic transmission reduces the risk of leaks, oil pressure drops, and malfunctions of the gear control system.

Characteristics of the used component

The offered oil sump comes from dismantling, which allows for maintaining the original manufacturer's specification while reducing repair costs. A used component of this type is particularly beneficial in the case of:

• post-accident repairs or repairs after mechanical damage to the lower part of the gearbox,
• services where replacing the sump along with the seal is required,
• restoring the factory configuration of the drivetrain in compact class Mercedes vehicles.

Using an original sump from dismantling promotes dimensional and material compatibility with the rest of the transmission components.

Benefits of using an original oil sump

Choosing a factory oil sump for the automatic transmission in a Mercedes W169/W245 provides a number of practical benefits:

• Full installation compatibility – holes, sealing edges, and mounting points correspond to the manufacturer's factory solutions.
• Stable oil operating conditions – the properly shaped bottom and walls of the sump support correct circulation and cooling of the transmission fluid.
• Seamless integration with accessories – matching the factory filter, bolts, and sealing elements reduces installation time.

Thanks to this, the gearbox repair can be carried out in a predictable manner, maintaining operating parameters close to factory standards.

Expanding service within the drivetrain system

When replacing the oil sump in an automatic transmission, it is worth considering a comprehensive service, including checking the condition of the oil, filter, and seals. Such an approach allows for reducing the risk of repeated dismantling and optimizing maintenance costs in the long term.
